Puisano ea theory mabapi le tlhahlobo ea botsitso ba aerosol e hlahisitsoeng ke Arrhenius formula
Mokhoa o hlokahalang oa hore lihlahisoa tsa rona tsa aerosol li hlahisoe ke ho etsa tlhahlobo ea botsitso, empa re tla fumana hore le hoja tlhahlobo ea botsitso e fetile, ho ntse ho tla ba le likhato tse fapaneng tsa ho lutla ha kutu tlhahisong ea bongata, kapa mathata a boleng ba lihlahisoa tse ngata.Joale na ho ntse ho na le moelelo ho rona ho etsa tlhahlobo ea botsitso?
Re tloaetse ho bua ka 50 ℃ likhoeli tse tharo tsa tlhahlobo ea botsitso li lekana le lilemo tse peli tsa potoloho ea tlhahlobo ea theory ka mocheso oa kamore, joale boleng ba theory bo tsoa kae?Foromo e hlokomelehang e lokela ho boleloa mona: foromo ea Arrhenius.Arrhenius equation ke lentsoe la lik'hemik'hale.Ke mokhoa o matla oa kamano lipakeng tsa sekhahla sa karabelo ea lik'hemik'hale le mocheso.Litloaelo tse ngata li bontša hore foromo ena ha e sebetse feela ho karabelo ea khase, karabelo ea mokelikeli oa mokelikeli le karabelo e ngata ea multiphase catalytic.
Mongolo oa foromo (exponential)
K ke lebelo le tsitsitseng, R ke molar gas constant, T ke thermodynamic thermodynamic, Ea ke matla a bonahalang a ho kenya tshebetsong, mme A ke ntho e ka pele ho exponential factor (e tsejoang hape e le frequency factor).
Ho lokela ho hlokomeloa hore Arrhenius' empirical formula e nka hore activation energy Ea e nkoa e le ntho e sa fetoheng ho mocheso, e lumellanang le liphello tsa liteko ka har'a mefuta e itseng ea mocheso.Leha ho le joalo, ka lebaka la mefuta e mengata ea mocheso kapa mekhoa e rarahaneng, LNK le 1/T ha se mola o otlolohileng o motle.E bontša hore matla a ho kenya a amana le mocheso 'me Arrhenius empirical formula ha e sebetse liketsong tse ling tse rarahaneng.
Na re ntse re ka latela mokhoa oa Arrhenius oa matla ka li-aerosol?Ho itšetlehile ka boemo, boholo ba bona bo lateloa, ntle le mekhelo e seng mekae, ha e le hantle, hore "activation energy Ea" ea sehlahisoa sa aerosol ke ntho e tsitsitseng e ikemetseng ea mocheso.
Ho latela Arrhenius equation, lintlha tsa eona tse susumetsang lik'hemik'hale li kenyelletsa lintlha tse latelang:
(1) Khatello: bakeng sa karabelo ea lik'hemik'hale e amang khase, ha maemo a mang a lula a sa fetohe (ntle le molumo), eketsa khatello, ke hore, molumo oa fokotseha, khatello ea li-reactants e ea eketseha, palo ea limolek'hule tse kentsoeng ka yuniti e eketseha, palo ea likhohlano tse sebetsang ka nako ea yuniti lia eketseha, 'me sekhahla sa karabelo sea potlakisa;Ho seng joalo, e fokotseha.Haeba molumo o lula o le teng, sekhahla sa karabelo se lula se le teng khatellong (ka ho eketsa khase e sa nkeng karolo tšebetsong ea lik'hemik'hale).Hobane mahloriso ha a fetohe, palo ea limolek'hule tse sebetsang ka molumo ha e fetohe.Empa ka molumo o sa khaotseng, haeba u eketsa li-reactants, hape, u sebelisa khatello, 'me u eketsa mahloriso a li-reactants, u eketsa lebelo.
(2) Mocheso: ha feela mocheso o ntse o phahama, limolek'hule tsa reactant li fumana matla, e le hore karolo ea limolek'hule tsa pele tse nang le matla a tlaase e be limolek'hule tse sebetsang, ho eketsa peresente ea limolek'hule tse sebetsang, ho eketsa palo ea likhohlano tse atlehang, e le hore karabelo e sebetse. sekhahla se eketseha (lebaka le ka sehloohong).Ha e le hantle, ka lebaka la ho eketseha ha mocheso, lebelo la motsamao oa limolek'hule le potlakisa, 'me palo ea likhohlano tsa limolek'hule tsa li-reactants ka nako ea yuniti ea eketseha,' me karabelo e tla potlakisa ho latela (sesosa sa bobeli).
(3) Catalyst: ts'ebeliso ea catalyst e ntle e ka fokotsa matla a hlokahalang bakeng sa karabelo, e le hore limolek'hule tse ling tse arabelang li fetohe limolek'hule tse kentsoeng, ho ntlafatsa haholo peresente ea limolek'hule tse reactant ka bophahamo ba yuniti, ka hona ho eketsa lebelo la li-reactants ka makhetlo a likete.Negative catalyst ke se fapaneng.
(4) Ho tsepamisa maikutlo: Ha maemo a mang a tšoana, ho eketsa mahloriso a li-reactants ho eketsa palo ea limolek'hule tse entsoeng ka yuniti e le 'ngoe, kahoo ho eketsa ho thulana ka katleho, sekhahla sa karabelo se eketseha, empa peresente ea limolek'hule tse entsoeng ha e fetohe.
Lintlha tsa lik'hemik'hale tse tsoang likarolong tse 'nè tse ka holimo li ka hlalosa hantle karohano ea rona ea libaka tsa corrosion (corrosion ea gas phase, liquid phase corrosion le interface corrosion) :
1) Karolong ea khase ea khase, le hoja molumo o ntse o sa fetohe, khatello ea eketseha.Ha mocheso o ntse o phahama, ts'ebetso ea moea (oksijene), metsi le propellant lia eketseha, 'me palo ea likhohlano e eketseha, kahoo ho senyeha ha karolo ea khase hoa matlafala.Ka hona, ho bohlokoa haholo ho khetha li-inhibitor tse nepahetseng tse thehiloeng ho metsi tse thehiloeng metsing
2) mokelikeli mohato kutu, ka lebaka la ho kenngwa tshebetsong ha mahloriso e ile ea eketseha, litšila tse ling li ka 'na (tse kang li-ion hydrogen, joalo-joalo) ka sehokelo fokolang le ambalaji thepa potlakisa thulana hlahisa kutu, kahoo khetho ea mokelikeli mohato antirust moemeli lokela ho nkoa ka hloko. e kopantsoe le pH le lisebelisoa tse tala.
3) Interface corrosion, e kopantsoeng le khatello, activation catalysis, moea (oksijene), metsi, propellant, litšila (joalo ka li-ion hydrogen, joalo-joalo) karabelo e felletseng, e bakang kutu ea sebopeho, botsitso le moralo oa sistimi ea foromo ke ea bohlokoa haholo. .
Khutlela potsong e fetileng, ke hobane'ng ha ka linako tse ling tlhahlobo ea botsitso e sebetsa, empa ho ntse ho e-na le bothata ha ho tluoa tabeng ea tlhahiso ea bongata?Nahana ka lintlha tse latelang:
1: moralo oa botsitso oa sistimi ea foromo, joalo ka phetoho ea Ph, botsitso ba emulsification, botsitso ba saturation joalo-joalo.
2: litšila tse teng linthong tse tala, joalo ka liphetoho tsa li-ion tsa hydrogen le chloride ion.
3: botsitso ba thepa e tala, ph lipakeng tsa lihlahisoa tse tala, boholo ba ho kheloha ha litaba joalo-joalo.
4: botsitso ba makotikoti a aerosol le li-valve le lisebelisoa tse ling tsa ho paka, botsitso ba botenya ba lesela la plating, phetisetso ea thepa e tala e bakoang ke ho phahama ha theko ea thepa e tala.
5: Hlahlobisisa ka hloko tlhahlobo e 'ngoe le e' ngoe tekong ea botsitso, le haeba e le phetoho e nyane, etsa kahlolo e nepahetseng ka papiso e otlolohileng, ho hōlisa ha microscopic le mekhoa e meng (ena ke bokhoni bo haellang ka ho fetisisa indastering ea aerosol ea lapeng hajoale)
Ka hona, botsitso ba boleng ba sehlahisoa bo kenyelletsa likarolo tsohle, 'me hoa hlokahala ho ba le sistimi ea boleng bo felletseng ho laola boema-kepe bohle ba phepelo (ho kenyeletsoa maemo a theko, maemo a lipatlisiso le nts'etsopele, maemo a tlhahlobo, maemo a tlhahiso, joalo-joalo) ho fihlela maemo a boleng. leano, e le ho netefatsa botsitso ba ho qetela le ho lumellana ha lihlahisoa tsa rona.
Ka bomalimabe, seo re batlang ho se arolelana hona joale ke hore tlhahlobo ea botsitso e ke ke ea tiisa hore ha ho na mathata a tlhahlobo ea botsitso, 'me tlhahiso ea bongata e tlameha ho se be le mathata.Ho kopanya lintlha tse ka holimo le tlhahlobo ea botsitso ea sehlahisoa ka seng, re ka thibela boholo ba likotsi tse patiloeng.Ho ntse ho na le mathata a emetseng hore re hlahlobe, re a fumane le ho a rarolla.E 'ngoe ea lintho tse hohelang li-aerosol ke hore batho ba bangata ba lebelletsoe ho rarolla liphiri tse ngata.
